INCA Case Study: No Fines Properties, Manchester

In January 2022, Structherm were invited to provide their specialised knowledge for the renovation of 150 residential properties in Manchester. These properties, constructed using Wimpey No-Fines concrete, required refurbishment, specifically through the application of an External Wall insulation system (EWI) with a brick effect and textured render finish. The existing EWI, installed approximately two decades ago, no longer met the current standards. Additionally, the previous system had suffered from vandalism, making the properties unattractive to the local residents.

Solution & Specification

Structherm Ltd developed a fully customized solution to offer a cost-effective alternative to the removal and installation of a new system, enabling an overclad approach. They designed a unique and tailor-made ArtBrick^TM finish that could be adjusted precisely according to the specific requirements of the client.

Installation & Challenges

The rising material and labour costs and the economic climate at the time were all a challenge for Structherm.  There was also the added complication of making the old EWI system contribute to the thermal performance of the new system whilst ensuring that the product conforms to current standards.

Winter working and inclement weather were also a challenge.  Along with coordination with other trades as ASHP’s and other measures were installed. Prominent city location adjacent to the Etihad Stadium meant challenging traffic conditions and restrictive parking. Also, dealing with the nuances of an ‘industry first’ and the learning curve that comes with installing a new system over the top of an old one.

The End Result

The residents were delighted with the thermally efficient and visually appealing homes, as they experienced enhanced comfort in terms of living temperatures. Moreover, they were particularly pleased with the significant savings on their energy bills, which brought them great satisfaction with the excellent work that was achieved by Structherm Ltd. 

The effectiveness of the environmental and sustainability aspects in this project were demonstrated by the significant cost/environmental savings that were achieved through the avoidance of disposing of the materials that would typically be discarded. Significant embodied energy was saved by not needing to remove and dispose of the existing EWI system. Embodied energy refers to the total energy consumed throughout their lifecycle, including the energy required for extracting, processing, manufacturing, transporting, and installing the materials used in their construction, but also their disposal. It takes into account both the direct and indirect energy inputs associated with the building’s materials and components.

Quotes

“The Manchester No-Fines properties were a challenge for Westdale, not only due to the changeable winter weather, but also the complication of dealing with an existing EWI system that was decades old. Looking back on the completed works, we’re very proud of what we achieved. Now the residents can relax knowing their homes are using much less energy than before with their new thermally efficient home”
